No matter in terms of language, speech, meeting, host or live performance, it can be used in any situation, place and time to get rid of complex on-site layout needs and provide the most reliable links, and present the most authentic sound restoration at every moment. The main applications for business conmunication: conferences, primary and secondary education, hotels, higher education, religious places, enterprises and governments.

FEATURES:

Real time noise suppression: real-time elimination of background noise, so that users can fully focus onthe voice in the call.

Automatic frequency coordination: the system automatically scans the available spectrum and selects clear and clean transmission channels to achieve the best performance.

Interference avoidance: the system can detect and avoid unexpected interference, and channel adjustment can prevent interference to audio.

RF efficiency: perfect PLL RS stabilization technology can provide better sound quality and wider dynamic range, to ensure the highest quality sound in any environment.

Encryption: standard AES-128 encryption of audio and data can ensure the privacy of conference content Data control: provides control functions for central control, audio and speaker equipment, realizing video tracking, voice control. Etc.

User-friendly interface: high-definition TFT color display screen provides a complete overview of system information, and enable users to set up shortcuts.

Power monitoring: real-time power monitoring of each transmitter, ensuring uninterrupted use in the field. Electronic volume: 30-level electronic volume control, can precisely control the volume of each channel. Multi-platform systems work together: the receiver provides 2/4/8 channels. The transmitter provides handheld, backpack, and desktop conference microphones. Users can mix and match them freely.
One-key frequency matching: one-key fast data synchronization between the receiver and the transmitter, convenient and fast.

Multiple audio interface outputs: each channel has an independent balanced audio output XLR (male), a mixed output TS(6.35mm 2-core), and a cascade output TS (6.35mm 2-core).

Audio cascade: When multiple receivers are used in stacked, all receivers can achieve unified audio management through the cascade audio interface.
